Judy Holmes Textiles has decided to use a c-Chart to monitor the number of defects per pair of jeans produced by their manufacturing process. The c-Chart should be constructed with 3-sigma control limits. The operations manager randomly samples one pair of jeans at 10 successively selected time periods and counts the number of defects on the pair of jeans. Answer Table O In Control Control Chart Step 4 of 7: At the next time period, 23 defects were detected on the randomly selected pair of jeans.

Responses are cross-tabulated by educational attainment (DEGREE). a. What percentage of those surveyed felt teen sex was always wrong? b. What percentage of those with less than a high school diploma felt teen sex was always wrong? c. What percentage of those with a graduate degree felt teen sex was always wrong? d. Interpret the gamma statistic. e. Using chi-square, test the null hypothesis that DEGREE and TEENSEX are statistically independent. Set alpha at .05.
